Just seeing what everyone prefers for sensitivity on COD4...

Mines at a 3 right now.

Any higher than three for me and I overshoot every guy I aim for.

I use one notch beneath the max, whatever number that is.

I can spin around in circles quick enough to make spectators sick :)

I use whatever the default is.
Don't need it quick on COD4,

Default.

default.

depends... on a normal game I have it on default, but on hardcore I have it on full.

i use 1 less than default

i have mine at 7, though 10 is fun sometimes too.
